In the drawings-Figure l is a side elevation of an explosion motor towhich my improvements are applied; Fig. 2 is an elevation at rightangles to Fig. 1. g

In the operation of explosion engines in which liquid fuel, is employedit has been found desirable to'warm the carbureted mixture beforeintroduction into the explosion The present invention accomplishes thisresult by extending the induction passage along the wall of the waterjacket for the en ine cylinder whereby it will be substantially heatedby the water within the jacket. As shown, A 1s a multi-cylinderexplosion engine, and B is the water jacket surrounding the cylinders. v

C is a removable plate forming a. portion of thewall of the water jacketand through which access may be obtained to the interior,

said plate being secured by suitable means,

with the ports E is preferably cast integral with the plate C, and, asshown, is of a Y- shaped form. The 'stem F of the Y extends outward anddownward from the plate C and is adapted for direct attachment to theSpecification of Letters Patent. Patented Aug. 23, 1910.

the Y lie adjacent to the plane or the plate C and receive heat directlytheref' om by conduction. At their upper ends these branches G and Gextend beyond the upper edge ofthe plate C and are provided with flangebearings H for coupling them to the engine casing and in registrationwith the ports E.

It will be apparent that the induction conduit, and particularlytheportions G and G thereof, will constantly receive heat from the waterin the jacket, and will be maintained at substantially the sametemperature. Thus the carbureted mixture passing throughthe conduit willbe warmed before entrance to the cylinders.

\Vhat I claim as my invention is:

1. The combination with an explosion engine provided with a waterjacket, of a remova of said jacket, and an induction conduit formedintegral with and extending along the exterior of said plate and'havingits opposite ends communicating respectively with the carbureter and theinlet for the engine.

2. The combination with an explosion enmova le plate forming a portionof the wall of said jacket, an induction conduit formed.
